Microstructures constructed from SU-8 polymer and produced on CaF2 base plates have been developed for microchip-based analysis systems used to perform FTIR spectroscopic detection using mid-IR synchrotron radiation. The high brilliance of the synchrotron source enables measurements at spot sizes at the diffraction limit of mid-IR radiation. This corresponds to a spatial resolution of a few micrometers (5â€“20 Î¼m). These small measurement spots are useful for lab-on-a-chip devices, since their sizes are comparable to those of the structures usually used in these devices. Two different types of microchips are introduced here. The first chip was designed for time-resolved FTIR investigations of chemical reactions in solution. The second chip was designed for chip-based electrophoresis with IR detection on-chip. The results obtained prove the operational functionality of these chips, and indicate the potential of these new devices for further applications in (bio)analytical chemistry.

A synchrotron radiation based technique is use to study the density distribution at the detonation front and its neighborhood for condensed explosives. Particular data are obtained on the structure of the detonation front in TNT, RDX, and an alloy of TNT with RDX; a comparison of the data with...

The synchrotron radiation emitted in the infrared range from a bending magnet of the third generation storage ring ELETTRA is studied in detail by simulation techniques. Edge effects are taken into account. Preliminary experimental checks on an existing port for beam diagnostics are reported....

In order to develop an intense far-infrared radiation source, a high quality electron beam has been studied at Tohoku University, Sendai. The bunch length of the beam expected is very much shorter than terahertz (THz) wavelength, so that coherent spontaneous emission of synchrotron radiation...

Understanding and controlling the structural anisotropies of injection-molded polymers is vital for designing products such as cantilever-based sensors. Such micro-cantilevers are considered as cost-effective alternatives to single-crystalline silicon-based sensors. In order to achieve similar...

Electromagnetic radiation between 300GHz and 10THz holds a great deal of promise as a screening and detection medium, but has proved difficult to produce. People are interested in gaining access to the region between the far infra-red at 300GHz and 10THz, as the radiation is non-ionising and...

Infrared cameras with passive, uncooled sensor chips utilize the longwave infrared (LWIR) range of the electromagnetic spectrum with wavelengths between 8 and 14 Î¼m for image generation. The reason for this is that every object at room temperature is self-luminous at that wavelength....
